TOMELLOSO is operated by Tomelloso Best Service S. L.

What it's used for

  • The address space carries local internet access services in Tomelloso, Spain, as indicated by the registrant name and netnames ES-TOMELLOSO-20160310 and ES-RATEMAN-20171120.
  • The AS announces 2048 IPv4 addresses across 2 prefixes with 2 observed neighbours, a ratio consistent with a small local access provider rather than a transit hub.
  • Traffic from this AS consists of residential and local business subscribers in the Tomelloso area, served via the operator's local infrastructure.

Notable

  • Registrants for the two announced prefixes differ: Tomelloso Best Service S. L. holds 185.142.220.0/22, while RATEMAN S.L. holds 185.232.180.0/22, suggesting either leased space or a corporate relationship between the two entities.
  • The address inventory is compact, comprising two /22 blocks totaling 2048 addresses, all located in Spain.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,849 prefixes, as published 2026-10-30. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
